Minimization Algorithm of Unate Logic Functions

Unate logic functions is an especially case of logic functions. For logic functions optimization, it costs mor spaces and times, spending of memory is increase on two power by input variables. According by characteristic of unate logic functions, this paper introduces an algorithm of unate logic functions optimization and presents a method of algorithm realization. It analyzes influence factor of unate functions logic optimization efficiency. The software system overpasses the testing of right validate. The results of experimentation is proved to be correct and efficient. It is good for reduce spending of memory spaces and times. Optimizing of effect is reduced by increasing numbers of input variable in case of the same numbers of output variable、 products and don’t-care gene, and by increasing numbers of don’t-care on case of the same numbers of input variable、output variable and products. The optimizing of effect is increased by increasing numbers of products on case of the same numbers of input variable、output variable and don’t-care gene.
